Which describes a primary role of the pioneer species in an ecosystem?
The primary role of pioneer species in an ecosystem is to establish a foothold or foundation for other species to colonize and establish themselves in the area. They are usually the first species that colonize a barren or disturbed area, such as a recently formed volcanic island or a cleared forest, and they play an important role in changing abiotic factors to make the environment habitable for other species. They also help in the accumulation of soil and nutrients, which further supports the growth of other plants and enables the establishment of a more diverse ecosystem.
